The identifier of the Amazon EC2 security group for the Amazon EMR service to access clusters in VPC private subnets.

Instance Attribute Details

#additional_master_security_groups ⇒ Array<String>

A list of additional Amazon EC2 security group IDs for the master node.

Returns:

(Array<String>)
—

A list of additional Amazon EC2 security group IDs for the master node.

#additional_slave_security_groups ⇒ Array<String>

A list of additional Amazon EC2 security group IDs for the slave nodes.

Returns:

(Array<String>)
—

A list of additional Amazon EC2 security group IDs for the slave nodes.

#ec2_availability_zone ⇒ String

The Availability Zone in which the cluster will run.

Returns:

(String)
—

The Availability Zone in which the cluster will run.

#ec2_key_name ⇒ String

The name of the Amazon EC2 key pair to use when connecting with SSH into
the master node as a user named \"hadoop\".

Returns:

(String)
—

The name of the Amazon EC2 key pair to use when connecting with SSH into the master node as a user named \"hadoop\".

#ec2_subnet_id ⇒ String

To launch the cluster in Amazon VPC, set this parameter to the
identifier of the Amazon VPC subnet where you want the cluster to
launch. If you do not specify this value, the cluster is launched in the
normal AWS cloud, outside of a VPC.

Amazon VPC currently does not support cluster compute quadruple extra
large (cc1.4xlarge) instances. Thus, you cannot specify the cc1.4xlarge
instance type for nodes of a cluster launched in a VPC.

Returns:

(String)
—

To launch the cluster in Amazon VPC, set this parameter to the identifier of the Amazon VPC subnet where you want the cluster to launch.

#emr_managed_master_security_group ⇒ String

The identifier of the Amazon EC2 security group for the master node.

Returns:

(String)
—

The identifier of the Amazon EC2 security group for the master node.

#emr_managed_slave_security_group ⇒ String

The identifier of the Amazon EC2 security group for the slave nodes.

Returns:

(String)
—

The identifier of the Amazon EC2 security group for the slave nodes.

#iam_instance_profile ⇒ String

The IAM role that was specified when the cluster was launched. The EC2
instances of the cluster assume this role.

Returns:

(String)
—

The IAM role that was specified when the cluster was launched.

#requested_ec2_availability_zones ⇒ Array<String>

Applies to clusters configured with the instance fleets option.
Specifies one or more Availability Zones in which to launch EC2 cluster
instances when the EC2-Classic network configuration is supported.
Amazon EMR chooses the Availability Zone with the best fit from among
the list of RequestedEc2AvailabilityZones, and then launches all
cluster instances within that Availability Zone. If you do not specify
this value, Amazon EMR chooses the Availability Zone for you.
RequestedEc2SubnetIDs and RequestedEc2AvailabilityZones cannot be
specified together.

Returns:

(Array<String>)
—

Applies to clusters configured with the instance fleets option.

#requested_ec2_subnet_ids ⇒ Array<String>

Applies to clusters configured with the instance fleets option.
Specifies the unique identifier of one or more Amazon EC2 subnets in
which to launch EC2 cluster instances. Subnets must exist within the
same VPC. Amazon EMR chooses the EC2 subnet with the best fit from among
the list of RequestedEc2SubnetIds, and then launches all cluster
instances within that Subnet. If this value is not specified, and the
account and region support EC2-Classic networks, the cluster launches
instances in the EC2-Classic network and uses
RequestedEc2AvailabilityZones instead of this setting. If EC2-Classic
is not supported, and no Subnet is specified, Amazon EMR chooses the
subnet for you. RequestedEc2SubnetIDs and
RequestedEc2AvailabilityZones cannot be specified together.

Returns:

(Array<String>)
—

Applies to clusters configured with the instance fleets option.

#service_access_security_group ⇒ String

The identifier of the Amazon EC2 security group for the Amazon EMR
service to access clusters in VPC private subnets.

Returns:

(String)
—

The identifier of the Amazon EC2 security group for the Amazon EMR service to access clusters in VPC private subnets.
